i really want to know if there ANY mod that add mod to realm (and if its possible)
Right now, no. Wait for either Optifine or Forge to come out with 1.9 support before wondering about other mods I'd say.

Only client mods work with Realms. Only! Nothing else.
Provided there are any client mods avaialble for the current latest Minecraft version.
I'm back ... maybe. Part-time? Give me some time to catch up.
Some notes: https://paste.ee/p/UYdwN outdated as heck. Might fix it some day. Most should still apply.
Running jars from command prompt also Jarfix
No support over PM. Just because. Don't even bother, you'll be ignored.
