new to game i need information

[casual]

i started the game yesterday i played for few hours, am still in beginner class

if i learn skills from rogue class then i change class to warrior then do i keep my rogue skills?

also how to unlock the master class? i can only see beginner and advance class

also if i level up one class lets say rogue become level 10 then i change class to warrior then will warrior start at level 1 or level 10

also is there a way to lose a trait and gain a new trait?

If you change classes, you only retain skills from skill trees that are mutually present in both classes. Any skills from skill trees that are exclusive to the previous class will be refund the skill & a skill point.

Master classes are unlocked later in story missions (I believe the first several are unlockable after finishing the 6* main story mission, while the rest are unlockable after the 7* main story mission).

When you change classes, you retain your adventurer's level.

Certain negative traits on unique characters can be removed and replaced with positive traits via certain actions on certain story missions. GreenGuy confirmed just a little bit ago on a different post that the Frail, Dumb, and Deathwish traits have a chance to disappear each day too (after certain conditions are met, you can find the thread titled "Hidden Talent Report" to see his full response there). You can gain new traits via a multitude of events, assignments, during training (again see "Hidden Talent Report"), and just randomly each day (Scarred trait).
