Twilio does not store your contacts, so there is no way to import contacts. When you want to send an SMS message you provide the number you want to send the message to, the Twilio number you are sending from and the body of the message. There is no need for a contact.
Within Twilio Notify, which is a way to send bulk notifications, you can create Bindings. A Binding is a resource that binds an identity to an address and an address type, for example an phone number for an SMS or an APNS device token for push notifications on iOS. Once you have a number of bindings stored, you can send a notification to them.
Also how do you know the phone number you have for a contact is a WhatsApp number?
When using the WhatsApp API to send messages, you must receive explicit opt-in from your users that you can contact them via WhatsApp. So, you should not try to search through existing contact numbers to find out whether they are also a WhatsApp number, instead, you should get your user's consent to send to their WhatsApp number and record the number then.

Can I send SMS text messages using all the different phone numbers of my US based users?

All my users are in the United States. When someone signs up on my website they enter their cell phone number. Can I use the user's own cell phone number to send a SMS text message via twilio?
I was reading the twilio documentation about subaccounts and I couldn't determine if this was possible or not. They make it sound like you can only send texts using a narrow range of phone numbers.

Today, you can only send text messages from phone numbers you've provisioned from Twilio. We've got a FAQ article that describes why.
You can make phone calls from either a Twilio provisioned phone number, or a verified phone number.
Hope that helps.
