हम अभी स्टेशन जाएँगे, और समय पर पहुँचेंगे।

With verbs of motion like जाना (to go), Hindi often uses the destination directly, without को.

• घर जाना = to go home
• स्कूल जाना = to go to school
• स्टेशन जाना = to go to the station

So हम अभी स्टेशन जाएँगे is completely natural.

By contrast, with पहुँचना (to arrive/reach), Hindi often uses a postposition such as पर:

• स्टेशन पर पहुँचेंगे = will arrive at the station

In your sentence, स्टेशन is understood as the destination of जाएँगे.

Yes. अभी often means now, right now, or immediately, and it can definitely appear with the future tense.

Here it gives the idea of:

• now / at this moment
• right away
• shortly

So हम अभी स्टेशन जाएँगे means something like We’ll go to the station now or We’re going to the station right away.

Hindi does this very naturally, even though English learners may expect now to go only with present tense.

जाएँगे is the future form of जाना (to go) for हम (we).

Very roughly:

• dictionary form: जाना
• future stem: जा
• ending for we / masculine or mixed-gender plural: -एँगे

So:

• हम जाएँगे = we will go

You may also see the spelling जाएंगे in casual typing, but जाएँगे is the more standard spelling.

Because the subject is हम (we), the verb must be plural.

So:

• मैं जाऊँगा / जाऊँगी = I will go
• हम जाएँगे / जाएँगी = we will go

And similarly:

• मैं पहुँचूँगा / पहुँचूँगी = I will arrive
• हम पहुँचेंगे / पहुँचेंगी = we will arrive

In your sentence, -ेंगे shows plural and is used for a masculine or mixed-gender group.
If the speakers were all female, you would normally say:

• हम अभी स्टेशन जाएँगी, और समय पर पहुँचेंगी।

Because Hindi often omits repeated subjects when they are already clear.

So this is normal:

• हम अभी स्टेशन जाएँगे, और समय par पहुँचेंगे।

It means:

• We will go to the station now, and (we) will arrive on time.

English often repeats the subject less rigidly too, but Hindi does this very naturally. Once हम has been established, the second clause can leave it understood.

समय पर means on time.

Literally:

• समय = time
• पर = on / at

So the phrase is roughly on time or at the proper time.

This is a very common fixed expression:

• समय पर आना = to come on time
• समय पर पहुँचना = to arrive on time

A very common everyday alternative is वक़्त पर, which means the same thing.

They describe two different parts of the action:

• जाना = to go
• पहुँचना = to arrive / reach

So:

• हम अभी स्टेशन जाएँगे = We will go to the station now.
• समय पर पहुँचेंगे = We will arrive on time.

English sometimes uses go more loosely, but Hindi often separates the movement itself (जाना) from the final arrival (पहुँचना).

Because Hindi normally puts the verb near the end of the clause.

This sentence has two clauses joined by और (and):

1. हम अभी स्टेशन जाएँगे
2. और समय पर पहुँचेंगे

Each clause ends with its own verb:

• जाएँगे = will go
• पहुँचेंगे = will arrive

That is very normal Hindi word order. English uses Subject + Verb + Object much more often, but Hindi generally prefers Subject + Object/Adverb + Verb.

और means and and joins the two future actions.

So the structure is:

• हम अभी स्टेशन जाएँगे
  and
• समय पर पहुँचेंगे

It makes the sentence flow naturally as a compound sentence. In some contexts, Hindi can leave out और if the connection is obvious, but here और is the most straightforward and natural choice.

It is a very common loanword from English, written in Devanagari as स्टेशन.

Hindi uses many everyday borrowed words this way, especially for modern places and objects. So even though it comes from English, it behaves like a normal Hindi noun in the sentence:

• स्टेशन जाना = to go to the station

You could also say रेलवे स्टेशन if you want to be more specific, but स्टेशन by itself is extremely common.
