How to configure multiple subdomain with SSL in Apache?

Configuration:

Debian
Apache2
Wildcard SSL for: *.example.com
subdomain: a.example.com, b.example.com.
1 dedicated server
Websites are in NodeJS (ProxyPass...)

For now, i'm able to get a.example.com to work. But how i can make a.example.com AND b.example.com working on the same server ?

/etc/apache2/site-enable/a.example.com.conf
<VirtualHost  *:80>
  ServerName a.example.com
  Redirect permanent / https://a.example.com
</VirtualHost>
<VirtualHost  *:80>
  ServerName www.a.example.com
  Redirect permanent / https://a.example.com
</VirtualHost>
Listen 443

<VirtualHost *:443>
 ServerName a.example.com
 ServerAlias www.a.example.com

 ProxyRequests off
 LimitRequestLine  150000
 LimitRequestFieldSize 150000
 <Proxy *>
  Order deny,allow
  Allow from all
 </Proxy>

 <Location />
  ProxyPass http://localhost:4949/
  ProxyPassReverse http://localhost:4949/
 </Location>

 SSLEngine on
 SSLProtocol all -SSLv2 -SSLv3
 SSLCipherSuite ALL:!DH:!EXPORT:!RC4:+HIGH:+MEDIUM:!LOW:!aNULL:!eNULL

 SSLCertificateFile   /etc/ssl/2__.example.fr.crt
 SSLCertificateKeyFile  /root/XXXXXX.key
 SSLCertificateChainFile    /etc/ssl/1_root_bundle.crt 
</VirtualHost>

UPDATE --- If i try this:

/etc/apache2/site-enable/b.example.com.conf
<VirtualHost  *:80>
ServerName b.example.com
Redirect permanent / https://b.example.com
</VirtualHost>
<VirtualHost  *:80>
ServerName www.b.example.com
Redirect permanent / https://b.example.com
/VirtualHost>

Listen 443

<VirtualHost *:443>
 ServerName b.example.com
 ServerAlias www.b.example.com

 ProxyRequests off
 LimitRequestLine  150000
 LimitRequestFieldSize 150000
 <Proxy *>
  Order deny,allow
  Allow from all
 </Proxy>

 <Location />
  ProxyPass http://localhost:6949/
  ProxyPassReverse http://localhost:6949/
 </Location>

</VirtualHost>

I'm getting this

[....] Restarting web server: apache2[Thu Jul 21 14:58:01 2016] [warn] module passenger_module is already loaded, skipping

(98)Address already in use: make_sock: could not bind to address [::]:443

--- UPDATE

I removed Listen 443 on b.exemple.com.conf

But now, i have this:

a.example.com ---> b.example.com
b.example.com ---> b.example.com

The problem is that when i try to access to a, i'm redirected to b

What i'm doing wrong ?

/etc/apache2/site-enable/b.example.com.conf
<VirtualHost  *:80>
ServerName b.example.com
Redirect permanent / https://b.example.com
</VirtualHost>
<VirtualHost  *:80>
ServerName www.b.example.com
Redirect permanent / https://b.example.com
/VirtualHost>

<VirtualHost *:443>
 ServerName b.example.com
 ServerAlias www.b.example.com
