I need to practice small talk.
I'm mostly at dance practice in my free time.

'during my free time' is also good.

So I guess the other 2 are grammatically wrong?

No. The grammar is OK, but those sentences are inappropriate. Native speakers don't say them.

Note that there are thousands of grammatically correct sentences that are never used. Being grammatically correct is just the beginning. After that, sentences have to be meaningful and idiomatic, in other words, how English speakers actually use grammatical sentences.
