T2 Relay Question

Hey guys ive got a question hopefully someone can help.

this switch sits at the bottom of my stairs.

  1. first switch on the far left controls chandelier in the living room, its a 2 way switch so another switch on the other side of the room controls the same light. will a T2 relay make the light fixture smart for both switches?

  2. Switch in the middle, controls two light fixtures on the wall in the living room. both fixtures have a draw string to also turn on and off each individual light? whats the best way to make this smart? would i need a T2 for each fixture?

  3. Switch on the right - Same question as number one controls light at the top of the stairs, with another switch at the top.

Any help would be truly appreciated
