Can these bulbs be used to replace the christmas led of the 5mm that are concave style?

... Depends entirely on the specifics of the "Christmas LED" (and what you mean by "concave style"). If the original string shares the same electrical characteristics as these, then sure--but there's no way to randomly guess what kind of LEDs you're trying to replace.

Do you have leds of 1.5 volts available?

I do not have any but there might be some out there. Try DigiKey or Mouser electronics.

Can I use a 9v battery

Dear customer, voltage range of these diodes are: R/Y 2.0-2.2V; B/G/W 3.0-3.2V. 9v battery could only be used with proper resistors. Thank you for asking and hope this answer could be helpful.

These + a 2-3 volt DC button battery and it lights up? Aside from a switch and the connections, anything else needed?

depends on the purpose of your use of the LED. I used several to illuminate a model r/c airplane with two 1.5 AAA batteries and an off and on switch. They can be soldered together plus to minus leads in series or connected by lengths of wire. Note: some require different voltages identified on the container lid
