How to manage multiple textures in OpenGL ES 2.0?

I have a OpenGL ES 2.0 app with 6 different textures. What I need is to draw and move them all at the same time. I was able to do it, but the movement was laggy because I was loading the bitmaps into the textures all the time. For each texture, I do the following on the Render method:

    setupImage(texture1);
    GLES20.glVertexAttribPointer(mPositionHandle, 3, GLES20.GL_FLOAT, false, 0, vertexBufferT1);
    GLES20.glVertexAttribPointer(mTexCoordLoc, 2, GLES20.GL_FLOAT, false, 0, uvBufferT1);
    GLES20.glDrawElements(GLES20.GL_TRIANGLES, indicesT1.length, GLES20.GL_UNSIGNED_SHORT, drawListBufferT1);

And on the setupImage method, I do this:

    // Create the bitmap
    int id = mContext.getResources().getIdentifier("drawable/texture1", null, mContext.getPackageName());
    Bitmap bmp = BitmapFactory.decodeResource(mContext.getResources(), id);

    // Bind texture to texturename
    GLES20.glActiveTexture(GLES20.GL_TEXTURE0);
    GLES20.glBindTexture(GLES20.GL_TEXTURE_2D, textures[0]);

    // Set filtering
    GLES20.glTexParameteri(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MIN_FILTER, GLES20.GL_LINEAR);
    GLES20.glTexParameteri(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MAG_FILTER, GLES20.GL_LINEAR);

    // Set wrapping mode
    GLES20.glTexParameteri(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_WRAP_S, GLES20.GL_CLAMP_TO_EDGE);
    GLES20.glTexParameteri(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_WRAP_T, GLES20.GL_CLAMP_TO_EDGE);

    // Load the bitmap into the bound texture.
    GLUtils.texImage2D(GLES20.GL_TEXTURE_2D, 0, bmp, 0);

    // Free bitmap
    bmp.recycle();

This is obviously wrong. However, I don't know how to load each bitmap into a different texture and then how can I switch the active texture on the Render method.

So, how can I achieve this, in order to display and move all the six textures and have a fluid movement?
