To sign 'how can I help', place your dominant hand in a fist with the thumb pointing up (an 'A' handshape) and rest it on your flat, upward-facing non-dominant palm. Move both hands forward together toward the person you are offering help to. Because this is a question, make sure to use a questioning facial expression, such as slightly furrowed eyebrows and a slight head tilt, to convey the full meaning of the phrase.
Sign 'hello', then use the directional 'help' sign moving toward the person while maintaining a friendly, questioning facial expression.
Point to the person, sign 'lost', and then move the 'help' sign toward them with your eyebrows slightly furrowed to ask the question.
Sign 'time', 'free', point to yourself, and then offer the 'help' sign forward toward the person you are addressing.

No, you don't need to sign 'how' separately. In ASL, offering help is often expressed simply by moving the 'help' sign toward the person and using a questioning facial expression to convey the entire phrase.
Both hands move together because 'help' is a directional verb in this context. The non-dominant hand acts as the supportive base for the dominant hand, and moving them as a single unit shows the support being offered to the other person.
You should use a questioning expression. Slightly furrow your eyebrows, tilt your head forward a bit, and maintain eye contact to clearly indicate that you are asking a question rather than just making a statement.
