Mystery stones from Brazil-help needed with identification

[Drahokam]

I was given a box of stones a family member brought from Brazil in 1970-1974 when he was there building petroleum pipelines. Couple amethysts, and some red / brown maybe garnets.

The ones i am wondering about are in the attached photos. The yellow stone is a pale warm yellow, black reflections are from my phone.
The orange stone is orange with some brown, has nice glow, all black spots are from the phone.
The white stone- not much sparkle, i am not sure if CZ would have been an option back in early 1970.

thank you!

Just some rough guesses.
Orange is most likely garnet and deepening on size and which type might be $$$
hessonite $ spessartite $$$
The rest are likely Beryl.

Thank you Karl, i appreciate it. The orange one is 11x9mm. It has significantly more brown than my spess but the color is pleasing.

Nice size and it looks nice.
The color between the 2 can overlap in the brown/orange or orange/brown range so just going by color is not conclusive in that color range.
