To sign "Joshua", you will fingerspell the name. Start by extending your pinky finger to trace a "J" shape in the air. Then, smoothly form the remaining letters: "O", "S", "H", "U", and finally "A". Keep your hand steady in front of your shoulder as you spell.

No, standard proper names do not have universal signs. You will always fingerspell 'Joshua' unless referring to a specific person who has been given a unique name sign by the Deaf community.
No, you should not mouth the individual letters (J-O-S-H-U-A). Instead, you can naturally mouth the full word 'Joshua' as you fingerspell it, which provides extra context for the person reading your signs.
Speed comes with practice, but clarity is always more important. Practice fingerspelling 'Joshua' slowly in front of a mirror, focusing on the smooth flow between letters rather than rushing.
