I was playing $1/2 with my friends

Just curious about this situation

Here is thing.

UTG opend to $22 and UTG+1 shoved like $26.

UTG+2 shoved like $48 and Hijack who covered UTG flat called $48.

My friend said UTG only can call because of $26 which is under bet all in.

Is this correct? I thought UTG was able to go all in.

Gimme the answer plz

Thanks.
