Can i use this amp to bypass my knackered active amp ie just usse the shell and connect direct to the speaker?

Yes I bought it to do this myself just had to open the sub and disconnect the plate amp. Used the speaker connections for convenience wired to be a passive sub.

Can I use this amplifier with active subwoofer only? (Without connecting anything to speaker output?)

No it need a full range speaker and then used with an active sub woofer

Can this work with tpa3116 amplifier (ns-15g) and nobsound 6j2 vacuum tube preamplifier? i want to add a subwoofer to my hi fi.

as long as your current amplifier has a sub out channel or any such output that can provide a signal such as a tape out.

Can i connect a 100 w bookshelf speaker and 150w active subwoofer in the full frequency mode ? at the same time ? thx

In full frequency mode the unit is just a straight forward amp and will drive a passive bookshelf as normal. Since you are using an active sub it will tap of the signal going to the bookshelf again as normal.
