To sign 'Jaden', you will fingerspell the name using the ASL alphabet. Start with a 'J' by extending your pinky finger and tracing a hook shape in the air. Transition into an 'A' (closed fist with your thumb resting on the side), then a 'D' (index finger pointing up, other fingers forming a circle with the thumb). Follow with an 'E' (fingers curled in toward the thumb), and finish with an 'N' (thumb tucked under the index and middle fingers).
Sign 'MY', then 'FRIEND', followed by 'NAME', and finally fingerspell J-A-D-E-N smoothly.
Fingerspell J-A-D-E-N, then sign 'COME' and 'PARTY' while raising your eyebrows to indicate a yes/no question.

Yes, generally you will fingerspell it. You would only use a single sign for 'Jaden' if you are referring to a specific person who has been given a unique name sign by the Deaf community.
Focus on clarity over speed. It is much better to spell slowly and clearly so your conversation partner can understand you, rather than rushing and blending the letters together.
Keep your hand comfortably at shoulder height, slightly to the side of your face. This placement allows the person you are signing with to easily see both your handshapes and your facial expressions at the same time.
